Highest temperature in Guangzhou on August 10?

Platform comparison

Market context

Guangzhou’s highest temperature on 10 August will be set by the reading at Guangzhou Baiyun International Airport, with the market resolving from the **Daily Observations** table on Weather Underground rather than the site’s headline day-high summary. That matters because intraday warmth in Guangzhou often peaks in the low-to-mid 30s Celsius in August, but the settlement temperature is the single maximum recorded observation, not an averaged or forecast value.[11][14][16]

The current **0% YES** crowd price is consistent with a very specific settlement rule: the outcome is not “will it be hot”, but whether the observed high lands in the exact temperature band that defines YES. Guangzhou’s August climate is typically hot and humid, with average highs around 33°C and frequent rain, so the event is usually framed by the day’s actual station trace rather than the month’s climatology.[2][5][18] Comparable weather markets can move sharply when a late-afternoon spike, a rain-cooled cap, or a station-report update shifts the final maximum by even 1°C.

For access and compliance, the legal frame is not the weather itself but the venue. German GlüStV analysis generally turns on whether a market is offered to users in Germany and how the operator is authorised or restricted there; for US users, CFTC reach is the key issue if the contract is viewed as a derivatives product rather than a pure gaming or event wager. On access, “no-KYC up to $1,500” means a user can typically trade only up to that cumulative threshold before identity verification is required, which improves entry friction but does not remove jurisdictional limits or source-based resolution risk.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Germany Legal has a different geo footprint.

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Germany Legal exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Germany Legal would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
